Figure 3. Relationship between RHC and echo-derived PVR.

Figure 3

Panel A. Linear regression demonstrates significant correlation between cath and echo PVR for all subjects (rho 0.75, p < 0.001). The correlation strengthens when stratified by FVC%/DLCO% ≥ 1.6, (open circle symbol, rho −0.87, p 0.003). Closed circle symbol represents FVC%/DLCO% < 1.6. Panel B. Bland-Altman plot for echo-derived PVR and RHC PVR.
